2. To design a spacecraft right takes an infinite amount of effort. https://t.co/vq5UeNPbo1

Rocket Lab have now tweeted a strong 14 times about their Mars Telecommunication Orbiter as opposed to Blue Origin's measly 10 times. This gap will surely be the reason Rocket Lab wins the contract; keep at it PR teams! (I will cry laugh if Marslink wins)

Some strong complements for Nancy Grace, which you know, happy for them. Valves also featured, some stuff about MMOD management, lunar power contracts, some hypersonics work for DOD (also did you know that NASA is now helping Anduril develop missiles)

Which is supposed to launch the human tissue experiment. https://t.co/S1BuC8HEOR Also guaranteeing that the Mars comm orbiter gravy train will not be affected by any MSR shenanigans. The protesting by either RL or Blue (or both) will be worse than HLS option A mark my words.

The NASA authorization act approved by the Senate Commerce Committee today includes a study of a human Mars mission—sort of.

So yes, the amendment does cancel EUS. But it also does some things. xEMUs is back on the menu. MSR is back with a $8B cost cap. Mars commercial missions that only Starship can fulfill "Mars-focused missions using commercially developed fully reusable heavy-lift launch systems"

The spacecraft went through an interesting sub-contractor history, where it started off with Momentus building the bus and Relativity launching the spacecraft. LM kicked Momentus off the contract, then switched to ABL. Then ABL gave up on launch and the mission died with it?

Was anyone else tracking that Lockheeds Cryogenic Demonstration Mission was cancelled? The last time the contract value increased was Feb 2024 and the only 2025 transactions were just cancelling subcontracts.I guess after losing HLS, LM didn't see the reason to continue?

SpaceX presentation on Starlink batteries. Starlink sat manufacturing/ops is cracked, insight into how they approach QC/design is cool. Interesting to consider how certain subsystems on a constellation can provide unique scale observations (see Stargaze) https://t.co/UvXB6WlqO6

We have a problem. Currently there is 2 four letter acronyms, RTLS and ASDS, to describe VTVL landing sites. But this landing doesn't fit into either category. It's a downrange land landing, so how about DRLL?

LANDSPACE failed to recover Zhuque-3's first stage on its maiden launch. But the launch was a success. The payload has been inserted into orbit! Congratulations 🎉

I had been wondering what future programs was up to beyond weird stuff with hydrogen storage and I guess this answers it. Granted, this is still just a patent; that's a long way from an actual committed to and built stage; but the ideas there. Also sunshields yay!

I am a little off put by the pressure-fed when they have that smexy bleed turbo machinery and my desire for Stage 2 to do everything. But maybe this is delightfully counter-intuitive where higher pressures allow for long duration storage as well as a bunch of other benefits.

The focus of this third stage is to host payloads on orbit for an extended duration with orbital maneuvers capability before returning them back to Earth; basically the X-37B. https://t.co/8qgpXNV0Ev https://t.co/JrdG7dY0UK https://t.co/JMLxtAiAwU https://t.co/A1HIjwrM1j

New patent from @stoke_space for a smaller pressure-fed version of their second stage to act as a third/in-space stage. David Biggs (one of the authors) is director of Future Programs at Stoke, so this appears to be the thrust of that business element. https://t.co/Ty107q59mI

H3 targeting 3 blocks, 1. Rideshare, 2. Cadence/production 3. Performance/orbit access. It's certainly strange seeing Ariane put 9-10 A6/year as the North star given what's happening in the US.

Firefly/NG presentation on Eclipse progress, they're happy with it (at least definitely compared to Alpha lol) I'm allergic to that 328s on Vira like damn how is it 20s lower than Merlin 1D.
